https://devzone.nordicsemi.com/f/nordic-q-a/1662/nrf51822-evaluation-kit-hardware-updateDo you think I could update PCA10001 V2.0.0 just by replacing the nRF51822 chip? I have more current chips lying around, and with a little rework I could be able to switch to the latest SDK. Many thanks!en-USTelligent Community 13Thu, 20 Feb 2014 09:45:51 GMThttps://devzone.nordicsemi.com/thread/7379?ContentTypeID=1Thu, 20 Feb 2014 09:45:51 GMT137ad170-7792-4731-bb38-c0d22fbe4515:348efe9a-2592-4e82-89e6-83014a3aaab6Ole Morten<p>Yes, this should be perfectly doable. If you switch from the first to second revision (from CA/C0 to FA/GC/G0), you can also remove the R1 resistor, since this pull-down is internal on the second revision.</p><div style="clear:both;"></div>
